Recent shootings at schools have raised public concern about school safety. Each year a National Crime Victimization Survey with indicators of school crime and safety is published which indicates that in 2016, students aged 12-18 experienced more victimizations (theft and nonfatal violent victimization) at school than away from school; victimizations are higher for males than for females; and there was more bullying reported in middle schools than high schools or elementary schools.

Acts of violence in schools and other public places have stunned the nation. Children, in particular, may experience anxiety, fear, and a sense of personal risk. They may also sense anxiety and tension in those around them — friends, family members, loved ones, caregivers and other adults who have a direct impact on the well-being of children.
